SVDO: Gives Simultaneous 1X Voice and EV-DO Data On Same Network
August 17, 2009 Leave a Comment

A SVDO, simultanious network carrying both voice and data was announced by the CDMA Development Group (CDG) today. The best part of this new type of technology is simultaneous 1X Voice and EV-DO Data. Unlike today’s GSM networks which are EV-DO, like Sprint and Verizon, are unable do both right at this time as the data network is interrupted for Voice calls. We also can’t take advantage of “live” services like caller-ID look-up programs.
“A complementary device enhancement known as simultaneous 1X Voice and EV-DO Data (SVDO) will also become available during the same timeframe and will enable CDMA2000 devices to access EV-DO packet data services while in an active 1X circuit-switch voice call. For example, users will be able to send emails or access the Web while on voice calls; phones with GPS can update maps or download real-time traffic information while on voice calls, etc. This device enhancement, which enables these concurrent voice and data services, is independent of the air link standard and infrastructure.” – CDMA development group.
